Granted: 2004-01-13
Abstract: A consumer digital video cassette recorder (210) may record an advanced television signal (09) having an MPEG-like signal format. The predictive nature of the MPEG-like signal format requires that additional I frame data be generated and recorded together with a normal play speed data stream (10) to facilitate non-standard speed, or trick play reproduction. Additional I frame data streams (121, 131, 141) are generated specifically for each replay speed and are written within recorded tracks to facilitate reproduction at the predetermined speeds. Various inventive methods for the derivation of full resolution and reduced resolution trick play data streams are disclosed. Inventive trick play data stream generation is disclosed for real time recording by consumer apparatus and non-real time normal and trick play data stream generation for use with pre-recorded digital media.

Abstract: A security label (20) with the sheet material (21) having a first major surface. An adhesive layer (26) containing an identifier medium (32) is coated on the first major surface. A barrier medium (22) is selectively applied on an exposed surface of the adhesive layer for at least partially blocking diffusion of the identifier medium from the adhesive layer into a substrate (30). A release liner (28) may be provided that extends substantially over the exposed surface of the adhesive layer. A method of preparing the security label includes applying a barrier medium in the form of an identifier pattern to a low energy surface material.  The low energy surface material is laminated to a security label having an adhesive layer containing an identifier medium. When the low energy surface material is removed from the adhesive layer, the barrier medium substantially transfers to the adhesive layer to block diffusion of the identifier medium into a substrate.

Granted: 2006-11-21
Abstract: This invention is a side wheel attachment (18) for removably attaching an auxiliary side wheel to a bicycle (10). The side whell attachment comprises a single structural rod which is folded in the desired shape, i.e. forms a helical torsion spring (22). In natural unbiased condition, the first and second ends of the spring rod extend generally perpendicularly to one another. The first end (20) of the spring is inversely U-shaped and tangentially engages by its web the rear axle (14) of the bicycle where it can be fixed after adjusting is vetical position relative to the bicycle. The second end (24) of the spring rod is rotatably engaged by the auxiliary side wheel, therefore acting as its axle. Both ends can angularly move relative to one another due to the helical spring. Therefore, in use, both auxiliary side wheels (installed on one side and the other of the rear bicycle wheel) and the rear bicycle wheel loaded by bicycle rider, always stay in contact with the ground so as to accomplish their rescpective tasks. The novelty of this invention resides in the structural simplicity of the side wheel attachment which is, as previously stated, constructed from a single structural rod.

Abstract: Methods and apparatus are provided for dispensing chemical material, and in particular, granular, agricultural material, from a moving device driven over terrain to be treated with the material. A metering system for dispersing the material includes on apertured metering disk positioned above a rotatable impeller. The apertured disk meters material from a product container, by gravity feed, onto the impeller below at a rate proportional to the linear speed at which the apparatus is driven to dispense material at a uniform density over the terrain. The metering disk is a component of a product container which is removably mounted to the device. The impeller rotates at a constant speed to disperse the deposited material at a uniform distance from the apparatus, and the position on which the material is deposited on the impeller is adjustable. A clutch permits the user to discontinue dispensing material from the device at the selection of the user, and automatically discontinues dispensing of material when the apparatus is driven in a reverse direction.
